Caesar Cipher code to:The Caesar Cipher code sheep.Caesar Cipher code to:Caesar Cipher code how to guess the search will start from the letter repeatedly before. Consider the first sentence of the letter 3 Where 2 or 3 are usually always is. The probability of repeated letters, including the letter is in English, A E I O U letter frequency appears in English most often N C D S T H L R.Vigenère cipher :Vigenère cipher is a cipher Vigenère encryption secret keys (Secret Key) or Symmetric Key Cryptography that relies on the same basic principle of the Vigenère cipher is Caesar uses the Key that is encrypted, the future by creating a Caesar Cipher from the letters that appear in the Key.Vigenère cipher :Vigenère cipher, for example, we have the Plaintext: ATTACK AT DAWN and use Keyword: LEMON take Plaintext into a pair with the same Keyword, the length of the Plaintext: ATTACK AT DAWN following Key: EM LXFOPV EF LEMONL ONLE Ciphertext: first-letter A RNHR is encoded with the Caesar Cipher Key letters, 2 L-T will be encrypted with the Caesar Cipher Key E letters, 3-T will be encrypted with the Caesar Cipher Key 4-letters M A Caesar Cipher is encrypted with a Key 5-letter O C Caesar Cipher is encrypted with a Key N and so on until the full sentence.Vigenère cipher :Vigenère cipher to decrypt it, do the reverse process of Caesar, but need to know the Keyword and Keyword Ciphertext: LXFOPV EF RNHR: LEMON led the Ciphertext with the same Keyword, length: Ciphertext: LXFOPV Key: EM EF RNHR LEMONL ONLE Plaintext: ATTACK AT DAWN the first letter-L will be decoded by the Caesar Cipher Key L letters 2-X will be decoded by the Caesar Cipher Key E letters, III-F will be decoded by the Caesar Cipher Key letters, 4 M-O will be decoded by the Caesar Cipher Key O the 5 letters-P will be decoded by the Caesar Cipher Key N and so on until the full sentence.
